IGF-1 DES Research Peptide

IGF-1 DES (des(1-3) IGF-1) is a truncated analogue of insulin-like growth factor-1 missing the N-terminal three amino acids. The literature documents dramatically reduced binding-protein affinity as a result, making it the tool of choice for research into localised, high-availability IGF signalling.

Like IGF-1 LR3, this is a recombinant-class protein where analytical verification is everything: our material is independently verified to ≥99% purity with MS identity confirmation at 7371.4 g/mol, and every vial ships with its batch-specific COA.

Supplied lyophilised in sterile vials with tracked UK delivery and cold-pack options available.

Orders placed before 4pm Monday–Friday are dispatched the same working day. Standard tracked UK delivery (1–2 working days) is £4.99, or free on orders over £25; next-working-day delivery is available at checkout.
